Using that to refer to a person isn’t technically wrong; it’s just considered “impolite.” Grammatical etiquette calls for the word who.

The missing apostrophe in judges will incur many editors’ wrath. And the quotation marks around Dancing and its capitalization lead me to believe the writer is referring to the TV show. But it just doesn’t make sense in that context. “Kim Kardashian’s dancing” or even “Kim Kardashian’s ‘dancing'” does make sense, given her performance last night.

I’m sure that they would have corrected the whole who-biz. When referring to a thing or group (even a group of people, like a team), don’t use who, use that or which. Of course, it is possible that the “losers” mentioned above are actually people. We all know some of those.
